The Ampzilla 2000 Second Edition embodies state-of-the-art execution of a monoblock power amplifier. On the muscle side, the Ampzilla uses twelve 250-watt output devices and a 2000VA custom designed and built transformer for each monoblock. As well, each monoblock has 100,000µf of power supply filtering with dual rectification. Utilizing a completely new variation of our Forward Gain topology to achieve unprecedented improvements in linearity, the new circuit is so smooth that it can actually be listened to open loop without feedback.

The Ampzilla 2000 Second Edition is conservatively rated at 300 watts into 8O and 540 watts into 4O, and is stable below 1O. With this much power, a pair can drive the most demanding speaker loads to thunderous levels as deftly as they can whisper the most delicate notes from higher sensitivity speakers.

The entire circuit is fully balanced from input to output and includes a unique new unbalanced-to-balanced converter for single-ended inputs. The captive industrial-grade 12 gauge power cord is selected specifically for the Ampzilla and is welded on for maximum conductivity and security, eliminating the hassle or expense of aftermarket cords. The Ampzilla 2000 Second Edition also sports a second set of binding posts for bi-wiring or -amplification. In sum, this proficient powerhouse is likely the last amplifier you’ll likely ever need.

“The Ambrosia and Ampzilla 2000 are by any standard statement products that can take their place among the finest amps and preamps money can buy.... If I were closing up shop tomorrow as a reviewer, I would buy them and live happily ever after. ”
